IMPROVEMENT IN APPARATUS FOR TRANSMITTING CHRONOMETRIC MOTION.

Specification forming part of Letters Patent No. 148,637, dated March17, 187u4; application filed September 25, 1873.

To all whom t may concern:

Be it known that I, HERMANN JULIUs WENZEL, of San Francisco, in theState of California, have invented an Improvement in Transmitting rIimeMovements to Distant Dials, of which the following is a speciiication:

In Letters Patent No. 140,661, granted to me, a lever, c, with cylindersc c', suspended at the ends, is employed, in connection with cups f fcontaining liquid, to transmit atmospheric pulsations to a distantapparatus that is moved by such atmosphere, and operates the dialmechanism.

In that patent, the action of the lever and clock movement is equalizedby vessels k upon the lever c, connected by a tube.

My present invention is an improvement upon the aforesaid apparatus; andconsists in a lever and variable Weight applied in connection with theclock mechanism so as to equalize the action of the mechanism, and thisweighted lever can be made to eounterbalance any number of cups andcylinders, so that the apparatus can be varied to suit the largest orsmallest number of connected clocks.

In the drawing, Figure l is a section of the cups and cylinders andequali'zin g mechanism, and Fig. 2 is a sectional plan of the same atthe line .c m.

The cups f f', cylinders c c, tubes g g are substantially the same as inthe aforesaid patent, and a reference is hereby made to the same for adescription of the mechanism that is acted upon at the distant dial, bythe air that is moved through the pipes g g', by the cylinders e c asthey are alternately raised and depressed by the lever c.

in a suitable frame, b', and to that lever the The lever c is upon afulcrum, a,

quadrant or are d is connected. The heartA cams b are revolved by themotor or clock movement, and operate, upon the rollers 2 and 3, to swingthe lever c and move the cylinders c e up and down. The are d isprovided with teeth to rotate the pinion Z and its shaft el, and swingthe lever m first one Way and then the other, and upon this lever m is amovable Weight, n. As the clock-Work is raising one cylinder, c, anddepressing the other one, c', the action of the air which has beencompressed aids in raising the nfeighted lever m, and, as it passes thevertical position, it aids in forcing the other cylinder c down, andcompressing the air and forcing it to the distant-dial apparatus. Byadjusting the position of the Weight n upon the lever m, the actionthereof can be rendered equal, or nearly so, to the reaction of theatmosphere and cylinder that is being immersed, and thereby themotor-clock will be relieved from inequality of strain.

This device is more easily varied than that in aforesaid patent, so thatan apparatus that is made fornsewith three dials can be adjusted if anadditional dial is added,instead of requiring a change in the apparatus.

I claim as my invention- The lever my and adjustable Weight n, incombination with the are d, lever c, cylinders c c', cups f f', and theactuatingcam Z), substantially as and for the purposes set forth.

Signed by me this 20th day of September, 1873.
